Greek compositions in WCCC 2014, Bern

This blog has special interest in Greek composers.
In this post we will see compositions that received distinctions in the composing tourneys of WCCC 2014, in Bern. In a previous post we saw that Argirakopoulos Themis, Manolas Emmanuel and Prentos Kostas had 1, 3 and 11 distinctions respectively. It so happens, that we had published a picture of these Greek composers together, in WCCC 2010.

Neutral pieces take the color of the playing side.
Circe Kamikaze : When a capture occurs, the capturing piece and the captured piece in this order
(King excluded, unless otherwise stated) must be replaced on their rebirth square if it is empty, otherwise, the piece vanishes.

The Judge said : "The solutions of this problem culminate in a fabulous quadruple check, which is already a highly noticeable record with only 9 units on the board. Besides, the diagonal-orthogonal correspondence is perfectly realized and we find, as in many problems, the traditional reciprocal battery creation with Rook and Bishop.The wQ arrives on the same square e8 at W3, but since the routes the wQ takes are different, it is not a defect. One defect however would be the passive nRa6".

Lion : Moving in Queen lines, it jumps over a hurdle and lands / captures in any free square immediately after the hurdle. The hurdle-color changing Lion, changes the color of the hurdle (except King or neutral piece) when jumping over it.

The Judge said : "Nice miniature. The white rook and Lion exchange functions in the mate".

SneK chess : When a Queen is captured, a Rook of the same side becomes a Queen. When a
Rook is captured, a Bishop of the same side becomes a Rook. When a Bishop is
captured, a Knight of the same side becomes a Bishop. When a Knight is
captured, the King (but not another royal piece) of the same side becomes a
royal Knight. When a Pawn is captured, the royal piece of the same side
becomes a King.

The Judge said : "Switchbacks of the bR and bB for re-blocking, Ideal mates. A little but lovely problem".

SPG : Given a game position, find all the moves since the start of the game. There is an upper limit on the number of the moves.

The Judge said : "« Only » 4 thematical checks but of the same nature : they are all battery checks without capture,
the most sophisticated nature of thematical moves. Very « professional » realization.".

SPG : Given a game position, find all the moves since the start of the game. There is an upper limit on the number of the moves.
Circe Parrain : In the next move following a capture, the captured unit (except a King) accomplish (from its capture square) an exact copy of that next move. If the arrival square is occupied or if the journey brings it out of the board, the captured unit vanishes.

The Judge said : "Cross-double check is clearly impossible in orthodox chess. Possibly other fairy conditions than
Circe Parrain allow to do it, but this problem will be a pioneer".

SneK chess : When a Queen is captured, a Rook of the same side becomes a Queen. When a Rook is captured, a Bishop of the same side becomes a Rook. When a Bishop is captured, a Knight of the same side becomes a Bishop. When a Knight is captured, the King (but not another royal piece) of the same side becomes a royal Knight. When a Pawn is captured, the royal piece of the same side becomes a King.

The Judge said : "Complicated combination of transformations to reach the final mating positions, each time by a different white Rook forming a Zilahi. Mutual captures by the wSb1/bBc2.".

SneK chess : When a Queen is captured, a Rook of the same side becomes a Queen. When a Rook is captured, a Bishop of the same side becomes a Rook. When a Bishop is captured, a Knight of the same side becomes a Bishop. When a Knight is captured, the King (but not another royal piece) of the same side becomes a royal Knight. When a Pawn is captured, the royal piece of the same side becomes a King.

Exercises of the day

Every day the website www.shredderchess.com offers to the readers of the blogs three easy chess exercises. They are given in three levels of difficulty, (L1, L2, and L3), and you may give the solution by moving the pieces with the mouse pointer. Below the diagram is then shown if the answer is correct or not.
